Encryption in a secure computerized gaming system

Abstract

The present invention provides an architecture and method for a gaming-specific platform that features secure storage and verification of game code and other data, provides the ability to securely exchange data with a computerized wagering gaming system, and does so in a manner that is straightforward and easy to manage. Some embodiments of the invention provide the ability to identify game program code as certified or approved, such as by the Nevada Gaming Regulations Commission or other regulatory agency. The invention provides these and other functions by use of encryption, including digital signatures and hash functions as well as other encryption methods.

Benefits of technology

The invention provides a way to securely store and verify game code and data on a platform specific to wagering games. It allows for secure exchange of data with a computerized gaming system and ensures that game program code is authenticated. The invention uses various electronic elements for security, such as digital signatures, encryption, hash functions, and message authentication codes. The method includes preparing a game data set for authentication by creating a control file with message authentication codes and a random seed value. The game data set must contain multiple files such as video, audio, coin counting, and button recognition. The gaming system includes a nonvolatile memory with an encrypted control file that includes program filenames, message authentication codes, and a random seed. The gaming controller decrypts the control file and authenticates the gaming program files during operation of the gaming system.

Problems solved by technology

The vast array of electronic video gaming apparatus that is commercially available is not standardized within the industry or necessarily even within the commercial line of apparatus available from a single manufacturer.

One of the reasons for this lack of uniformity or standardization is the fact that the operating systems that have been used to date in the industry are primitive.

To date, no manufacturer is known to have been successful in creating a universal operating system for converting existing equipment (that includes features such as reusable modules of code) at least in part because of the limitations in utility and compatibility of the operating systems in use.

The lack of a standard operating system has contributed to maintaining an artificially high price for the systems in the market.

Also, competitors cannot easily provide a single game that can be played on different hardware.

This verification technique therefore will not detect any changes that occur in the code that is executing because it tests the code residing in mass storage prior to loading into RAM.
